Systemd and tuning ondemand governor?

Question

I have a DESKTOP machine that I'd like to be a little more responsive. In the Arch wiki there's a good explanation of how to fine tune the ondemand governor which seems to suit my needs perfectly. The performance governor is a bit too much. The manual commands;
echo -n 15 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo -n 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
work very well.
Now I tried to create a systemd service doing the above;
[Unit]
Description=CPU frequency ondemand tuning
[Service]
ExecStart=echo -n 15 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
ExecStart=echo -n 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
[Install]
WantedBy=multi-user.target
When trying to start it systemctl complains "job failed. Invalid argument". I've tried single qoutes after echo, but no success. Is this possible in a service file? Google has no answer unfortunately.

Nope, no luck. Tried with two ExecStart= ... and with the two commands separated with ; which works in another service file. Error:
Loaded: error (Reason: Invalid argument)
      Active: failed (Result: exit-code) since Wed, 13 Jun 2012 13:23:00 +0200; 3min 52s ago
Since I'm running only systemd units and will not use rc.local.service I really hope tuning the governor is possible from a native unit file.
Hey! One of your commands after the ExecStart= ... works! I'll try the syntax ...
